The drilling will test for depth extensions of the Molyhil resource, which currently totals 2.38 million tonnes at a combined Tungsten-Molybdenum uncut grade of 0.80%. Magnetic modelling indicates that the Molyhil resource continues to a depth of at least 450m below surface. A number of geotechnical holes relating to tailings dam studies and hydrogeological investigations will also be completed as part of the DFS, which is due to be completed by mid-November 2006. Uranium Thor is also preparing for the commencement of uranium exploration at its five uranium projects in the Northern Territory. The portfolio covers a total area of 3,000 sq km, with the Hale River and Plenty Highway projects covering some 1,200 sq km of tertiary basin sediments and palaeo-drainage channels prospective for sandstone and roll-front style uranium deposits. The portfolio includes advanced target areas with previous uranium exploration history located in close proximity to existing discoveries.
